FLANGES SIMPLER, SAFER
Ramiz Selimbasic details a time-saving and cost saving alternative to welding
together. However, there’s an additional connection technology that is worth considering. T e High Performance
W
Flange (HPF) system is coordinated to common pipe sizes from 25 to 150mm diameter and wall thicknesses up to 20mm. It is designed for fl ange sizes ¾ to 5in hole patterns according to ISO 6162-1/2 (Code 61/62), ISO 6164. High-performance fl anges are manufactured as fi nished machined and type approved according to International Association of Classifi cation Societies (IACS). T is therefore results in consistently high precision and quality during processing, so that these components no longer have to be reworked at the installation site. T e best solutions for complex design
problems can often be found in nature. T e fl aring of a tube is similar to the shape of a branch where it joins the trunk of a tree. T e tube is fl ared by hydraulic axial
elding is still the most widely recognised method for joining pipe systems
High-performance fl anges have established themselves on the market as a time saving and cost-saving alternative to classic welding
pressure giving it a parabolic shaping, increasing from 10° up to 37°. T e initial gentle incline of the shaping guarantees additional safety against strong system vibrations. T e most essential part of the HPF connection is the locking fl ange design, which supports the pipe from the outside and provides additional protection against it tearing out of the connection. An insert is placed into this specially formed pipe. T is insert seals on the connection
side either via a special profi le seal or an O-ring and on the pipe side via an O-ring. T e insert has no toothed contour, which thereby makes repeated assembly work possible without any problems. T is HPF principle results in a series of practical advantages as Hans de Lang, production manager at Royal IHC, confi rms. In addition to ship construction, the company, which has been in existence since the 17th century, also manufactures
